SPECIFICATION forming part of Letters Patent No. 697,455, dated April15, 190.2.

Application filed August 30,1901. Serial No.73,862'. (No model.)

' cially the construction of the spindles thereof,

and to enable the spindles of an axle when Worn to be readily removedand replaced by a new set Without cutting and Welding or any otheroperation requiring the services of a skilled mechanic.

A further object of the invention is to provide'an axle of thischaracter in which the spindles may be advantageously constructed ofbrass or someother metal softer than iron or steel to provide a bearingwhich will not require the use of leather washers.

Thejnvention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claim hereto appended.

In the drawings, Figure 1 is a longitudinal sectional View of a portionof an axle constructed 'in accordance with this invention.

Fig. 2 is a detail perspective view of one of,

the removable sleeves or skeins which form the spindles. Fig. 3 is avertical sectional view on the line 3 3 of Fig. 1.

Like numerals of reference designate corresponding parts in all theiigures of the drawings.

1 designates a metal axle designed for use on carriages, Wagons, andother vehicles and provided at each end with a tapering arm 2, adaptedto receive a removable spindle sleeve or skein 3, which has a taperingbore or opening extending longitudinally through it and conforming tothe configuration of the axlearm 2. The axle 1 is designed to receive anordinary Wooden axle-bed 5, and the sleeve 3, which may be of anydesired exterior coniguration, is provided at its inner end with a lowerarm or extension 6, located beneath the axle and extendinglongitudinally thereof, as clearly shown in Fig. 1, and secured to thebody portion of the axle by means of an .body portion of the axle.

axle-clip 7. I The arm is provided with alongitudinal recess 8,extending from the bottom of the bore or opening 4 of the sleeve 3 andterminating short of the end of the arm to form a shoulder 9 forengaging a corresponding shoulder 10 of an enlargement 11 of the Theenlargement 10, which is arranged at the bottom of the body portion ofthe axle, is segmental in crossa section, being provided With a curvedlower face, and the recess 8 is curved in cross-section to conform tothe configuration of the enlargement. The arm is engaged with anddisengaged from the enlargement of the bottom of the axle. When the armis in engagement with the enlargement of the bottom of the axle, theshoulders 9 and 10 abut, and the sleeve is securely locked againstlongitudinal displacement. The arm is provided at opposite sides withprojecting ears 12, through which pass the sides of the axle-clip 7. Theperforated ears extend laterally from the arm, and project beyond theside faces of the axle, and the axle-clip holds the spindle againstlaccidental rotation, and the arm serves as a clipplate for the saidaxle-clip. When it is desired to remove the sleeve, it is only necessaryto remove the clip 7 and partially rotate the sleeve. The otheraxle-clips do not have to be removed, and the operation does not requirethe services of a blacksmith or other skilled mechanic. The inner end ofthe sleeve is preferably provided at opposite sides withWrench-receiving faces 13 to enable it to be readily engaged by a wrenchor other tool. The outer end of the sleeve is provided with a reducedthreaded portion 14, adapted to receive an axle-nut 15 of the ordinaryconstruction. The sleeve may be provided with any desired exteriorconfiguration, and it is preferably provided at its top with alongitudinal oil-groove 16, and it has a spiral groove 17 extendinglongitudinally of it. These grooves may be omitted or arranged in anyother desired manner. An axle-box 1S of a hub (not shown) is arranged onthe spindle sleeve or skein, as clearly shown in Fig. 1, and the saidsleeve may be constructed of brass or other material softer than steelor iron, and by constructing the sleeve -in this manner it isunnecessary to use leather Washers to pre vent the wheels from rattling.

IOO

It Will be seen that the removable spindlesleeves are exceedingly simpleand inexpensive in construction, that they are adapted to be readilyremoved when Worn without removing the body portion of the axle and theintermediate clips thereof and Without necessitating cutting and weldingthe axle. It will also be clear that the removable spindles or sleevesare securely held in place on the tapered arms of the axle and that theymay be advantageously constructed of brass or other material softer thansteel or iron.

The combination of an axle provided with an enlargement forming ashoulder at its inner end and having a curved outer face, and a sleevearranged on the axle and provided with an arm or extension having acurved y my own I have hereto affixed my signature in 25 the presence oftwo Witnesses.
